0.28 inch 10A 0-100V Dual LED Voltmeter Ammeter Blue Red with Onboard Diverter (10A)

Product description:

Features:

1. High precision, high reliability, suitable for high-end applications
2. With reverse protection, then anti-burn
3. 10A voltage current meter itself built-in shunt
4. Voltage measurement range: DC 0-100V
5. Current measurement range: 0-10A, 0-50A, 0-100A
6. Display Voltage and current simultaneously in different colors, red for Voltage, Blue for current (the current is Measured in the negative rail)
7. Require external power supply; with reversed connection protection
8. Ground wire of testing end and power supply terminal is the same wire; quick refresh of about 500 MS/time
9. With built-in shunt, has Voltage and current calibration potentiometers

Applications:

Suitable for automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement

Note:

1. The voltage between the thin red and thin black lines must be within DC 4.5-30V
2. The ammeter can only be connected to the negative of the device under test
3. It is unsuitable to use this meter to test current less than 1A ,if you use it to test ampere below 1A,it will have big error

Wiring:

1. Black line (thin): vacant or buck circuit (module) negative
2. Red line (thin): power supply+ Black line (thick): COM, common measuring
3. Red line (thick): PW+, measuring terminal voltage input positive
4. Yellow line (thick): IN+, current input+ (Please refer to the wiring diagrams for more details)

Specification:

1. Working voltage of Meter itself: DC 4-30V; Note: The maximum input voltage can not exceed 30V. Otherwise the meter will be burned
2. Voltage Measuring range: DC 0-100V; Voltage resolution (V): 0.1V
3. Current Measuring range: DC 0-10A; Current resolution (A): 0.01A
4. Operating temperature: -10 to 65° c; Operating Humidity: 10 to 80% (non-condensing); Working pressure: 80 to 106 kPa
5. Measure accuracy: 1% (±1 digit); Display:0.28" digital tube; Refresh rate: about 300mS/ times'
